Ace Test Series: Algorithm - Heap Sort
Q : What is the running time of heap sort for presorted input of size n? O(n) B) O(n^2) C) O(nlogn) D) O(logn) In the question they didn't mention if its a max or min heap and also they didn't mention if the presorted ... the time complexity would be O(n) and for decresing order it would be O(nlogn). Is the question incomplete or am i missing some concepts?
